JHK/2757727 UDDUYH United States Patent O" 3,250,317 HEATING AND COOLING MEANS FOR VEHICLES Jarrette A. Sudduth, Pensacola, Fla. (Rte. 3, Box 9, Wewahitchka, Fla.) Filed Apr. 6, 1964, Ser. No. 357,386 1 Claim. (Cl. 16S-42) My invention relates to novel means for cooling vehicles as for example cooling the interior of an automobile. I term such means a Polar Kool Kar.

It is an object of my invention to provide new and improved cooling means of thecharacter indicated.

Another object is to provide new and improved vehicle cooling means which utilizes ice rather than air conditioning equipment.

Still another object is to provide new and improved vehicle cooling means wherein the fan of a heater in the vehicle can be used to circulate cool or cold air.

All of the foregoing and still further objects and advantages of my invention will now be explained with reference both to this specification and to the drawings wherein:

FIGURE l is a side elevation View of my invention.

FIGURE 2 is a cross section )through the ice box of FIGURE 1.

FIGURE 3 shows a detail view of a modication which can be utilized in my invention when the vehicle in which it is installed has no heater.

Referring now to FIGURES 1 and 2, there is shown an automobile having an interior region 12 in which the driver and passengers (if any) sit in conventional manner. Underneath the front hood 14 is placed a fan carrying heater 16. The air outlet 22 from the heater is connected by a duct 18 to a discharge grill 20 communicating with the interior region 12. The air intake 24 of the heater is connected to a exible hose 26 which extends from the front hood back underneath the door 28 of the automobile into the rear trunk 30 thereof. The rear trunk carries an ice box 32 comprising a hollow rectangu- -l'ar box having ia top lid 34 which can be opened and closed, side walls 36 and bottom wall 38. These walls and lid are hollow and iilled with suitable insulation 40. The interior of the box carries ice 41. The box further has an lair intake tube 42 open at both ends and extending horizontally through one side wall of the box; an air outlet tube 44 open at both ends and extending horizontally through an opposite side wall of the box the inlet and outlet tubes being in vertical and horizontal alignment with each other; and a water drain tube 46 extending horizontally through the same sidewall as 3,250,317 Patented May 10, 1966 lCC the intake tube 42 but being positioned below this tube and `adjacent the bottom wall. The portion of tube 46 extending outside of the box terminates in a tube portion extending vertically downward.

Heater 16 carries'a fan 48 electrically operated and controlled in conventional manner. When the fan is operating, outside air is drawn by suction through tube 42 across the ice in the box wherein the air is cooled through tube 44, hose 26, intake 24 and is blown through the heater and passed through duct 18 and grill 20` into the interior region to cool same. As the ice melts, the vwater 43 so produced is discharged from the box through tube 46.

When the automobile has no heater, a spheroidal chamber having a fan 102 operated in the same manner as before and having aligned air intake and outlets 24 and 22 respectively can be substituted for the missing heater as shown in FIGURE 3.

When the automobile has its engine to the rear, the box can be placed under the front hood, the air intake tube then being connected to air inlet gul-l on the nont gull of the car, the outlet tulbe being connected directly to duct 18. As the car moves forward, air is forced through the box into the interior region and is cooled as before.

While I have described my invention with particular reference to the drawings, my protection is to be limited only by the terms of the claim which follows.

Having thus described my invention, l claim as new and desire to secure by Letters Patent:

In a vehicle having an interior region adapted for accommodating at least a driver and front and rear chambers separated from said region, the vehicle having an engine mounted in one of said chambers, a box mounted in the other chamber, said box being hollow and having a lid adapted to be opened and closed, and adapted to be at least partially lled with ice, and means to pass air from the outside of said vehicle through said box into said region, whereby said air is cooled as it passes through References Cited by the Examiner UNITED STATES PATENTS 2,108,391 2/19ss Rice azi-2.5 2,162,152. .ts/1939. wune 9s 2.4 2.319.002 5/1943 Kramer 98-24 MEYER PERLIN, Primary Examiner.
